SNFC CNTRL prefixes in area code 628
NANPA records 76 assigned NXX blocks to rate center SNFC CNTRL in area code 628, 39.4% of the 193 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 22 holders hold those blocks, the largest being TELEPORT COMMUNICATIONS AMERICA, LLC - CA (15), ONVOY, LLC - CA (14), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (7). The earliest assignment on record here is 2014-09-29 and the most recent 2025-04-28. 76 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area code 415 – overlay codes cover the same geography, so a rate center is served by all of them.
